10 The heart knoweth his own bitterness; and a stranger doth not intermeddle with his joy.
This agrees with 1 Corinthians 2:11, What man knows the things of a man, and the changes of his temper, save the spirit of a man? 1. Every man feels most from his own burden, especially that which is a burden upon the spirits, for that is commonly concealed and the sufferer keeps it to himself. We must not censure the griefs of others, for we know not what they feel; their stroke perhaps is heavier than their groaning. 2. Many enjoy a secret pleasure, especially in divine consolations, which others are not aware of, much less are sharers in; and, as the sorrows of a penitent, so the joys of a believer are such as a stranger does not intermeddle with and therefore is no competent judge of.
